Abstract

A composition and method for fixation or immobilization of aqueous hazardous waste material in cement-based materials (grout) is disclosed. The amount of drainable water in the cured grout is reduced by the addition of an ionic aluminum compound to either the waste material or the mixture of waste material and dry-solid cement- based material. This reduction in drainable water in the cured grout obviates the need for large, expensive amounts of gelling clays in grout materials and also results in improved consistency and properties of these cement-based waste disposal materials.

Method for primary cementing a well using a drilling mud composition which may be converted to cement upon irradiation

Patent Novak, L.H.

This patent describes a method for drilling and primary cementing a well comprising the steps of: drilling a well using a hollow drill string having a drill bit with at least one orifice communicating between the inside of the hollow drill string and the outside and located at the lower end of the drill string so as to produce a wellbore, circulating, while drilling, a drilling fluid comprising: at least one polymeric material containing at least one double bond and capable of being cross-lined with a monomeric cross-linking agent using a radioactive source, at least one monomeric cross-linking agent containingmore »« less
Zero free water cement composition and method

Patent Gandy, R.G.; Novotny, R.J.

A well cementing composition and method of cementing well bores are disclosed in which a slurry is first prepared utilizing cement, mixing water, and aluminum hydroxychloride in the range of 0.1 to 4.5 weight percent based on the dry weight of cement. The slurry thus prepared when pumped into place in the well bore has zero free water content thereby reducing the bridging or channeling in the cement column which is associated with free water formation.
